Definitions

  • the present invention relates to a high-pressure container, in particular for storing a fuel for a motor vehicle.
  • high-pressure containers for example for storing hydrogen as fuel for motor vehicles, can be constructed from an inner layer, the so-called “liner”, and a winding of fiber material around the liner.
  • blow molding and thermoforming technologies to produce a container. Production is then based on the forming of tubular or plate-shaped semi-finished products. These are brought into their final shape by negative pressure and/or positive pressure. For example, two half-shells can be produced that are joined together to form a container.
  • the materials used are mostly based on HDPE (high density polyethylene) or polyamides.
  • Liner materials An important distinguishing feature for liner materials is the mechanical low-temperature properties and the emission properties.
  • Monolayer materials such as polyamide have good barrier properties for gases, but do not have optimal low-temperature properties.
  • HDPE on the other hand, does not have a suitable barrier effect, but does have very good low-temperature properties.
  • polyamide is currently mainly used for applications in the hydrogen sector.
  • the suitable types available are also expensive due to the complex additives they require and are problematic when used at low temperatures.
  • High-pressure vessels for gases are subject to large temperature fluctuations during operation (filling, storing and emptying). This places high demands on the materials and in particular on the liner.
  • a pressure vessel comprising a polymeric impermeable lining and a reinforcing layer of a composite material which is arranged outside the impermeable lining at least one projection connected to the impermeable liner and the reinforcing layer to provide an opening of the pressure vessel, the impermeable liner being connected to the projection by a co-molded annular polymer-metal bonding zone.
  • the JP-H10-332085-A and the JP-H10-332083-A each disclose a pressure-resistant container having a gas-impermeable inner shell, a pressure-resistant outer shell covering the inner shell, and a mouthpiece attached to at least one pole of the container comprising both shells, the pole shoulder of the inner shell having a cylindrical neck projecting outwardly along the central axis of the inner shell; and the end of the projecting cylindrical neck being extended outwardly at right angles to the cylindrical neck to form an extension portion, the end of the extension portion being bent toward the shoulder of the inner shell to enclose the inner lower end of the mouthpiece.
  • a pressure vessel comprising a main body having a reinforcing portion having a tubular configuration and a lining portion made of resin and covering an inner peripheral surface of the reinforcing portion; an orifice ring formed integrally with the main body to communicate an inside and an outside of the main body with each other; and a valve inserted into the orifice ring on an inner peripheral side thereof, the orifice ring having a cylindrical boss portion and a flange portion protruding outward from an outer peripheral surface of the boss portion; and the lining portion formed integrally with the orifice ring and a flange sealing portion covering a bottom surface of the flange part, and includes a hub seal part formed continuously with the flange seal part to cover at least a part of an inner peripheral surface of the hub part in the axial direction thereof, the hub seal part including a hub-side collar part protruding outward, and a sealing member consisting of an elastic body is arranged in a space between an inner
  • the high-pressure vessel comprises a cylinder as a central part, wherein the cylinder consists of a multi-layer composite plastic which comprises a barrier layer, wherein the high-pressure vessel further comprises at least one half-shell at an axial end of the cylinder, wherein the half-shell consists of a multi-layer composite plastic which comprises a barrier layer, wherein the half-shell further comprises a substantially rotationally symmetrical insert part, namely a boss part, wherein the insert part has a foot part at the end of the insert part facing the interior of the container, which foot part has a larger diameter than a central part of the insert part, wherein the foot part essentially has a Forms a hollow cone or hollow cylinder and at least one first groove or depression filled with the multilayer composite plastic of the half-shell runs around a vertical inner circumference of the foot part, at least in sections.
  • a multilayer composite is used as the material for the liner, both in the middle part formed by the cylinder and in at least one, preferably both, axial end regions of the container.
  • Such multilayer plastics can be easily formed into a half-shell by means of blow molding or deep drawing or vacuum forming.
  • the cylinder in the middle part can also be blow molded or extruded, for example.
  • a boss part is used which has a foot part with a larger diameter than an adjacent middle part of the boss part.
  • the foot part thus forms an undercut in relation to a multi-layer plastic liner introduced from the side of the foot part or the center of the container.
  • the base part is hollow on the inside, in the area of its longitudinal central axis, and therefore essentially forms a hollow cone or a hollow cylinder.
  • a first groove or depression runs at least in sections, for example in individual sectors, around the inner circumference, preferably also around the entire inner circumference of the hollow cylinder or hollow cone.
  • This groove or depression is filled with the multi-layer composite plastic of the half-shell.
  • a "depression" can be designed similarly to a groove, and in any case has at least one edge that acts as an undercut for the plastic behind it, so that the multi-layer plastic is held in a form-fitting manner behind the edge in the area of the inner circumference.
  • the multi-layer plastic of the liner which has a barrier layer, increases the tightness in the area of the transition between the plastic liner and the boss part.
  • the plastic in the first groove or recess arranged on the vertical inner circumference is well protected against detachment during operation of the high-pressure vessel, so that the good sealing properties of the vessel are particularly durable.
  • the high-pressure vessel therefore has good permeation properties even in the area of the transition to the boss part.
  • the production of the half-shell with embedded boss part and the entire high-pressure vessel is nevertheless possible in a cost-effective manner because, as will be described in more detail later, the plastic can be introduced by blow molding or vacuum deep drawing despite the undercut at the base of the boss part.
  • the foot part has at least one second groove which is filled with the multi-layer composite plastic of the half-shell, the second groove running at least partially around the base of the foot part near the inner circumference of the foot part, facing the inside of the container.

  • the foot part has at least one fourth groove which is filled with the multi-layer composite plastic of the half-shell, wherein the fourth groove is formed near the outer circumference of the foot part at the bottom of the foot part facing the interior of the container, at least in sections This groove also prevents the plastic from detaching from the boss part.
  • the multi-layer composite plastic of the half shell is preferably arranged axially on both sides of the foot part.
  • the boss part which is usually made of metal, is thus embedded in the plastic with the barrier layer.
  • the base part has at least one third groove which is filled with the multi-layer composite plastic of the half-shell, the third groove running at least partially around the cover surface of the base part facing the outside of the container.
  • this third groove also prevents the plastic from detaching from the boss part on the cover surface of the base part.
